Turning all JSON web services into JSONP web services

I created a very simple Google App Engine application on Friday that helps you when somebody built a JSON based web service but did not mind to make it JSONP compatible (JSONP is a standard to do cross domain AJAX requests and it is supported by all major JavaScript libraries).

To use it simply call:http://jsonpgateway.appspot.com/?url=YOUR_URLor:http://jsonpgateway.appspot.com/?url=YOUR_URL&callback=YOUR_CALLBACKto us a customized callback parameters.
